Pack Chainring Bolts Elevn 8.5x4mm Alloy Double Clamping

The Elevn Alloy Chainring Bolt Pack is a set of CNC-machined 7075-T6 aluminum chainring bolts for BMX cranks. With an 8.5mm bolt length and 4mm thread engagement, they suit thicker modern four-bolt rings and standard five-bolt rings, and hex sockets on both bolt head and nut let you tighten from whichever side is easier to reach.

Features

• Heat-treated 7075-T6 aluminum, lighter than steel bolts
• Double hex design: no need to hold the nut with a second tool
• Handy on cranks with limited wrench clearance
• Laser-etched logos that won't fade or peel
